An r'omoBILn SPEED covnnii gf Application ammary 25, 1927. 'se'riaignoj fiasco.

The present invention relatesto an auto mobilespeed governor of the type actuated by a fan belt,'and associated with the fuel regulating throttle for opening and closing the throttle valve'iinder predetermined con-v ditions. 1 g

I: More mthe invention has reference to a device of this character Which eludes a centrifugal speed governor con structed to automatically operate a novel mechanism which is connected with the throttle valve for permitting a maximum and I 1y 'improve'upon structures of this class by uniform speed of movement to be main tained whether running on the level surface or upaor down an inclined surface,

Myprin'cipali aim, is of course, to generalproviding a novel organization of details such'as have been carefully selected and as sociated to render the device advantageous from the standpoint of the nia'nufacturer' owing to features of compactness and convenience, simplicity, and efliciency in opera- The particular constructlon of each and every part aswell'as its ofiice'in the new arrangement, will become more read lyapparout from the following description and drawings." p

, In the drawihgs z- H I Figure 1 is a top plan view of the com plete device showing it associated with fragv the steering rod housing, '6 and 7 the cusi tomary control rods on opposite sides thereof.

The invention comprises a suitable supporting bracket 8 fastened to the motor block and carrying an appropriate bearing 9. Journaled for rotation in this hearing is a shaft 10 on one end of which is a flanged I pulley 11, over which the ordinary fan belt 12 is trained.

An arm 13 is connected with the bearing 9 and includes a portion 14 operating as an additional hearing. The shaft 10 extends through and beyond the last named bearing. Mounted on the extending end portion is a fork 15 which is fastened to the shaft for rotationtherewith. This fork operates as a carrier for the pivotally mounted centrifugal governor arm 16. a

These governor arm's arelocated on dia-' metrically oppositesidosi of a'sliding cap 17 fitted on the shaft 1.0 as shownrbetter in'Fig. 2. 'On one end 'ofthis ca'p is a collar 18 in which inwardlyextending fingers or guides ofthe governor arms 16am located); Incidentally the governor arms are connected together b'y a spring which resists the outward swinging movement; On the opposite end of the cap is a reduced'neck carrying a rounded head 19. l

The head'19 is adapted to engage in an adjustable screw '20 carried on the depending arm 21 of the bellcrank 22. This bell crank is' pivoted as at 23 to the free end por-' tion of the supporting arm 13. In this position i t'will benoticedthattheset screw 20 is adpistable'toward and from the head19 toregulate the sensitivity of operation. 1

Pivotally connected as at;25 to the horizontal arm24= of-the bell. crank is 'a' throttle operating arm 26 which is in turn'connected with a right angularly disposed control rod 27., The rod isjconnected with the crank arm 3 on the throttle valve'qfAlso' connected with this arm'26 is a link28 adjustablyconnected with the bell crank arm 24. This permits, the angularity of the arm 26' with respect to the arm 24fto be varied and retained-in adjusted position; y, i 'A relatively long coiled spring 29 is connected at one end to the intermediate portion of therod 27 andis anchored atxits opposite end 'on' the stationarypart 4.} The intermediate portion of this frame" is however, connected with a handopera-ted throttle lever 30. That'portion of the 'spring'betw'eenthe lever and the support 4 is under tension and be transmitted through the medium of the fan belt 12 to the small pulley 11. This will rotate the shaft 10 in its bearings. In so doing, the head or fork 15, rotates with the shaft, and when a certain speed is obtained, the governor arms will fly out in the direction of the arrows against the tension of the springs. 7

Obviously, the special construction of these governor arms will act upon the collar 18 to shove or slide the cap 17 outwardly upon the shaft 10. This will eventually bring the head 19 into engagementwith theadjusted set screw 20 and will rock thebell crank 22 upon its pivot 23. It follows that through the medium of the arm 26, and the rod 27, this throttle. valve will be actuated.

It. is obvious from the. foregoing description, that I have evolved and produced a novel automatically operating device controlled, by the propeller shaft of the engine for actuating the throttle valve. The device is exceptionally sensitive and capable of being adjusted so that it can be regulated or set for a certain maximum speed, whereby when this speed is exceeded, the device will come into play to cut down the charge and to cause the machine to resume the normal speed limit.

It is believed that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more. length description. is thought unnecessary. i 1

Minor changesv in rearrangement. of parts, shape, size, and mounting maybe resorted to within the scope of the adjoined claims.

Having thus described my invention, what I claim as. new is v 1. In. a speed regulator of the class described, a. bearing, a shaft mounted for rotation in said bearing, said shaft being provided with a pulley adapted to be driven by a fan belt, an attaching bracket for the bearing, a supporting arm connected with the bearing, a bell crank pivotally mounted on the supporting arm, an operating connection associated with one arm of the bell crank for a throttle valve, centrifugal governor actuated means on the shaft cooperable with the remaining arm of the bell crank, together with adjustable means carried by the last crank arm for cooperation with said means.

2. In a structure of the class described, a bearing and attachment means therefor, a supporting arm associated therewith, a shaft mounted for rotation in the bearing, a bell crank pivotally mounted on said supporting arm, a throttle operating arm pivotally connected to the bell crank, and an adjusting and retaining link connected with the bell.

crank arm and said operating arm, a throttle operating rod connected with; the operating arm and a governor actuated device, associated with the shaft and said bell crank- 3. In a structure of the class described,

bearing and attaching means therefor, a support ng arm associated therewith, a shaft mounted for rotation in the bearing, a bell crank pivotally mounted on said. supporting 7 arm, a throttle operating arm pivotally connected to the bell crank, an adjusting and retaining link connected with the bell crank arm and said operating arm, a throttle operating rod connected with the operating arm, and a governor actuated device associated with the shaft and said bell crank, said device comprising a slide, and an adjustable set, screw carried by the bell crank and co -operable with said slide' 4. In a structure ofthe class described, a bearing, a. bell crank, means for supporting the bell crank from saidbearing, a, shaft mounted for rotation in said bearing, a belt pulley on said shaft, a fork fixedly mounted on said shaft for rotation. with. said shaft,

centrifugal governor arms carried by the arms of the said fork,-said shaftprojecting through and beyond the arms of" said fork, a, cap slidably mounted on the extending end of said shaft, said shaft; having a, head on one end, said centrifugal governor a-IIIlSxllitY ing operating connection with the other end of the cap, throttle operating means. connected with one: arm of said bell crank, and an adjustable set screw carried the; other arm of the crank and cooperable witha head on said cap.

In testimony whereof I aflix my signature.
